- This control unit 218 is configured to monitor the presence or absence of a high voltage signal at the load tap 208.
- the system 200 further comprises a cut-off member of an electrical connection, such as a relay 220, arranged downstream of the low battery voltage 214, and in the immediate vicinity of said battery 214, and for switching off the low voltage supply of all the vehicle components, except the control box 218.
- a cut-off member of an electrical connection such as a relay 220, arranged downstream of the low battery voltage 214, and in the immediate vicinity of said battery 214, and for switching off the low voltage supply of all the vehicle components, except the control box 218.
- the control unit 218 is configured to control the relay 220 either in an open state or in a closed state.
- the control unit 218 is configured to control the relay 220:
- control unit 218 is furthermore configured to terminate a wintering-in phase as soon as a high-voltage signal is detected at the pick-up point. charge 208.
- the vehicle 202 comprises a user interface 222, for example in the form of a touch screen, for sending a winterizing order.
- a user interface 222 for example in the form of a touch screen, for sending a winterizing order.
- the order of winterization can be sent through a physical interface manipulated by a key for example.
- the system 200 further comprises a plug 224, remotely controllable, through a wireless or wired communication network 226, of the Internet type.
- a user 228 can control the socket 224 to supply the vehicle 202 with a high voltage signal in order to trigger, at a distance, the wintering output phase of the vehicle 202.
- the control of the socket 224 can be achieved through a user device of the computer or smartphone type.
- the low voltage battery can be a 12V, 24V or 48V battery.
- the vehicle may not be provided with a plug but a cable provided with a plug provided to plug into a socket provided on a charging station or a wall box, for example .
- the invention is not limited to the examples which have just been described.
- the vehicle may comprise a different number of storage modules.
